It failed. Trying different battery charger- showing 13.9 volts.
Does the map have to be in the TuneECU Map folder? It's in my downloads folder, but I navigated to it. I'm not used to Androids and can't figure out how to move the file. I select it, choose Move, but no dialog that lets me direct it to that folder.
I also downloaded through the app but the Map folder is empty. Is this even the Penner file, or is that the stock file? This shows when I navigate to the download of his file and choose Open.
